GENERAL INSPECTION
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts, and other fasteners. Also check for
fuel, oil, and coolant leaks. Use Table 11 as a general
maintenance guideline. For engine maintenance, refer to
the engine instruction manual.
AIR FILTER
Every 250 hours: Remove air filter element (Figure 23) and
clean the filter element with low pressure compressed air.
Air pressure must not exceed 30 psi (207 kPa). The filter
can be cleaned and reused for up to six times if properly
cleaned. Replace air filter if rips or tears are detected while
cleaning.
Air Filter Dust Indicator
The air filter indicator (Figure 23) is attached to the air filter.
When the air filter element is clogged, air intake restriction
becomes greater and the air filter indicator signal shows
RED. When indicator is red, replace filter immediately. After
changing the air filter, press the air filter indicator button
to reset.
